Our mission at Wildlife Informer is to share free information and pictures of wildlife with our readers. good swimmers- front flippers rotate for more power and maneuvering The broad horizontal tail flukes that provide the main propulsive thrust bear no anatomical connection to the lost hind limbs, but are a seperate and distint development. Platypus are up to 2 feet long and 4 pounds. If not, then you are in the right place to know them. Their rear flippers dont rotate like sea lions and walruses, so they scoot their bodies, using their front flippers to push themselves on land. Flippers are one of the principal control surfaces of cetaceans (whales, dolphins and porpoises) due to their position in front of the center of mass, and their mobility which provides three degrees of freedom.

These tubercles or bumps are known to increase the aerodynamic flow of water while causing less resistance. Animals that live in the water have evolved with special adaptations for mobility and survival in an aquatic environment.
